  8. Combining pesticides Risk undesirable effects • clogs • scum • ineffective • labels often list compatible chemicals

  9. Compatibility test • quart glass jar • use same water (pH, debris) • W-A-L-E • WP or WDG • Agitate • Liquid products • Emulsifiable concentrates

  10. Compatibility test • shake • Heat may indicate incompatibility • stand for 15 minutes

  11. Application with Hand Sprayer • gloves and long pants • walk backwards to avoid walking through the chemical

  12. Equipment cleaning • clean as soon as possible to prevent drying • rinsate pad to collect waste • If no pad, move around • keep wearing PPE

  13. Rinsates • Apply rinsate to labeled area • Still contains pesticide

  14. Personal cleanup • take shower and wash hair and clothes

  15. Worker Protection Standard (WPS) • Provide information and training (EPA approved)

  16. Worker Protection Standard (WPS) Restricted-Entry Intervals Posting • Notification of applications • Danger Pesticides and Peligro Pestididas • REI for low risk: 4 to 12 hours

  17. Worker Protection Standard (WPS) PPE • Employer provides PPE

  18. Worker Protection Standard (WPS) Decontamination Stations • Water (1 pint), soap and disposable towels • At most ¼ mile away

  19. Worker Protection Standard (WPS) Safety Poster

  20. Worker Protection Standard (WPS) Recordkeeping • Kept for 2 years • Date, brand EPA registration #, quantity, area, and pest • MSDS
